Method Detail

isReadOnly

public boolean isReadOnly()
                   throws javax.jmi.reflect.JmiException
Indicates whether the underlying tables can be updated through an update to this View.

setReadOnly

public void setReadOnly(boolean newValue)
                 throws javax.jmi.reflect.JmiException
Indicates whether the underlying tables can be updated through an update to this View.

isCheckOption

public boolean isCheckOption()
                      throws javax.jmi.reflect.JmiException
This field is meaningful only if the view is not ReadOnly. CheckOption indicates that the RDBMS will validate that changes made to the data verify the view filtering condition and belong to the view result set.

setCheckOption

public void setCheckOption(boolean newValue)
                    throws javax.jmi.reflect.JmiException
This field is meaningful only if the view is not ReadOnly. CheckOption indicates that the RDBMS will validate that changes made to the data verify the view filtering condition and belong to the view result set.

getQueryExpression

public org.omg.cwm.foundation.datatypes.QueryExpression getQueryExpression()
                                                                    throws javax.jmi.reflect.JmiException
The query associated with the View. The query result must match the set of Columns associated with the View (in parent class ColumnSet)

setQueryExpression

public void setQueryExpression(org.omg.cwm.foundation.datatypes.QueryExpression newValue)
                        throws javax.jmi.reflect.JmiException
The query associated with the View. The query result must match the set of Columns associated with the View (in parent class ColumnSet)
